Publication Non-Invasive assessment of short and ultra-short heart rate variability during different physical and physiological tests(Univ Zagreb, Fac Kinesiology, 2021-06-01) Alparslan, Tuncay; Arabacı, Ramiz; Görgülü, Recep; ARABACI, RAMİZ; GÖRGÜLÜ, RECEP; Spor Bilimleri Fakültesi; 0000-0001-8403-5742; 0000-0003-2590-4893; ABI-4831-2020; N-8905-2015The main aim of the present study was to determine the short- and ultra-short-term heart rate variability (HRV) during different physical and physiological tests and to compare HRV to different performance levels. The latter aim was to compare participants' short- and ultra-short-term heart rate variability before-, during-, and post-tests. Our hypothesis was that there would be a significant difference between test performance and HRV parameters, and the high performing group would have significantly higher HRV parameters than the low performing group. Fifty-three healthy men (Mage=26.9 +/- 4 years, Mheight=177.9 +/- 5.7 cm; Mweight=77.8 +/- 8.7 kg) were recruited in the current study. We completed the data collection procedure for each participant in four consecutive days. On day-1, anthropometric measurements were conducted and then participants performed isokinetic tests. On day-2, participants performed anaerobic tests; on day-3 equilibrium tests, and on day-4 aerobic capacity tests. The HRV records of all participants were obtained before, during and after all these tests. Based on the participants' performance, they were classified into two groups: participants in G1 had lower performance and those in G2 higher performance. A two-way repeated measures ANOVA yielded significant differences in HRV values obtained in the four different tests. There was a significant difference between fitness test performance groups in the variation of short- and ultra-short-term HRV parameters.Publication Acute effects of static stretching on peak and end-range hamstring-to-quadriceps functional ratios(Baishideng Publishing Group Inc, 2015-10-18) Şekir, Ufuk; Arabacı, Ramiz; Akova, Bedrettin; ŞEKİR, UFUK; ARABACI, RAMİZ; AKOVA, BEDRETTİN; Spor Bilimleri Fakültesi; Beden Eğitimi ve Spor Bölümü; 0000-0003-2735-8697; 0000-0003-1044-8805; R-5044-2018; ABI-4831-2020; AAI-4550-2021; AAM-4348-2020AIM: To evaluate if static stretching influences peak and end-range functional hamstring-to-quadriceps (H/Q) strength ratios in elite women athletes.METHODS: Eleven healthy female athletes in an elite competitive level participated to the study. All the participants fulfilled the static stretching or non-stretching (control) intervention protocol in a randomized design on different days. Two static unassisted stretching exercises, one in standing and one in sitting position, were used to stretch both the hamstring and quadriceps muscles during these protocols. The total time for the static stretching was 6 +/- 1 min. The isokinetic peak torque measurements for the hamstring and quadriceps muscles in eccentric and concentric modes and the calculations for the functional H/Q strength ratios at angular velocities of 60 degrees/s and 180 degrees/s were made before (pre) and after (post) the control or stretching intervention. The strength measurements and functional strength ratio calculations were based during the entire-and end-range of knee extension.RESULTS: The pre-test scores for quadriceps and hamstring peak torque and end range values were not significantly different between the groups (P > 0.05). Subsequently, although the control group did not exhibit significant changes in quadriceps and hamstring muscle strength (P > 0.05), static stretching decreased eccentric and concentric quadriceps muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). Similarly, static stretching also decreased eccentric and concentric hamstring muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). On the other hand, when the functional H/Q strength ratios were taken into consideration, the pre-intervention values were not significant different between the groups both during the entire and end range of knee extension (P > 0.05). Furthermore, the functional H/Q strength ratios exhibited no significant alterations during the entire and end ranges of knee extension both in the static stretching or the control intervention (P > 0.05).CONCLUSION: According to our results, static stretching routine does not influence functional H/Q ratio. Athletes can confidently perform static stretching during their warm-up routines.Publication Effects of intermittent hypdxic training on normoxic exercise performance in elite wrestlers(Scibulcom, 2015-01-01) Arabacı, Ramiz; ARABACI, RAMİZ; Spor Bilimleri; 0000-0001-8403-5742; ABI-4831-2020The aim of present study was to assess the effect of intermittent hypoxic training (IHT) on anaerobic power, aerobic capacity and dynamic muscular maximum strength (1-RM) in elite freestyle wrestlers. Thirty elite freestyle wrestlers (mean age 23.4 +/- 4.1 years; height 169.1 +/- 15.4 cm; body mass 74.2 1 +/- 10.4 kg) who competed in Turkish First Wrestling League voluntary participated in present study. A pre-post randomised controlled training intervention design was employed to analyse the effect of an IHT program on anaerobic power, aerobic capacity and dynamic muscular maximum strength. Subjects were randomly divided into two groups: the first group performed normal usual normoxic wrestling training ( sea level) during a 8-week period (CG), while the second group performed usual normoxic wrestling training plus an IHT program (twice a week) in similar to 2000 m altitude during a 8-week period (IHTG).In conclusion, the use twice a week of intermittent hypoxic training increased anaerobic power, 1-RM and aerobic capacity of elite freestyle wrestlers.Publication Long-term effects of wearing the elevation training mask on physical performance in young soccer players(Univ Ljubljana, Fac Sport, 2019-01-01) Girak, İbrahim; ARABACI, RAMİZ; VARDAR, TONGUÇ; TOPÇU, HÜSEYİN; Eğitim Fakültesi; Beden Eğitimi ve Spor Bölümü; AET-8842-2022; AAZ-4372-2021; ABI-4831-2020The aim of the present study was to investigate the effects of the 6-week soccer training in on-session on the physical performance (PP) in 17-19 years old soccer players wearing elevation training mask (ETM) during workout. A total of thirty-six healthy soccer players (mean age 17.81 +/- 0.89 years, weight 65.95 +/- 5.72 kg, height 177.06 +/- 4.56 cm and BMI 22.1 +/- 2 kg/m(2)) voluntarily participated in the present study. Participants randomly were divided into an experimental group (EG) and control group (CG). EG (n=14) used elevation training mask (R) 2 (set-up as 2750 m altitude, wear in 3 workout a total of 270 min/week), while CG (n=22) didn't use ETM during interventions. Two groups completed the same soccer training program. Alactic anerobic power (ALAnPw), maximal oxygen use, fatigue index, average power output (APO), speed and flexibility of participants were evaluated.After carried-out a 2x2 ANOVA analysis for changes between pre-test and post-test values of two groups, there were no significant differences (p>0.05) of ALAnPw (F = 0.168, eta(2) = 0.002), flexibility (F = 0.030, eta(2) = 0.001), fatigue index (F = 0.036, eta(2) = 0.001), APO (F = 0.029, eta(2) = 0.001), VO2max (F = 0.382, eta(2) = 0.011), and Speed (F = 0.023, eta(2) = 0.001) between EG and CG. In conclusion, the use of ETM during soccer practices can increase physical performance of young soccer players. However, these improvements were not more than improvements in conventional conditions.Publication The effects of 12-week eccentric and concentric strength training on the physical fitness characteristics of football players(Univ Ljubljana, 2022-01-01) Erol, Sadettin; Arabacı, Ramiz; EROL, SADETTİN; ARABACI, RAMİZ; Spor Bilimleri Fakültesi; ABI-4831-2020; GMK-7029-2022The aim of present study was to examine the effects of eccentric and concentric training applied to football players on some motor characteristics. A total of 23 university students playing soccer participated in the study voluntarily. Subjects were randomly divided into two groups; complex (ECCst) and contrast (CONst) training protocols. During 12-weeks, ECCst and CONst training groups performed strength training in addition to soccer training 3 days a week, over 7 hours (4-5 units). On the first day, one repetition maximum (1RM) strength tests of all subjects were measured respectively. On the second day, all athletes' height, body weight, body fat ratio, vertical jump, and sprint (20 m) tests performance tests were measured at the beginning and end of the 12-weeks study. As a result, although there was a statistically significant difference between the pre and post (lying leg curl, machine abduction, machine adduction 1RM) and vertical jump test of the subjects in both ECCst and CONst training group in terms of time effect, a significant difference was found in favor of the ECCst in the group x time interaction of ECCst training compared to CONst (p<0.05). There was no statistically significant difference between the groups in the (1RM leg extension) and 20 m sprint performance tests (p>0.05). As a result revealed that 12-weeks ECCst more effective than CONst in improving lower extremity strength and vertical jump of soccer players. There were similar increases in both ECCst and CONst in 1RM leg extension and 20m sprint.Publication Fluid consumption habits of elite athletes(Scibulcom, 2015-01-01) Arabacı, R.; ARABACI, RAMİZ; Spor Bilimleri Fakültesi; Beden Eğitimi ve Spor Bölümü; 0000-0001-8403-5742; ABI-4831-2020The objective of present study was to examine fluid consumption habits of elite Turkish athletes and compared total fluid intake of training (TD) and non-training (NTD) days. A total of 142 male and 103 female Turkish elite athlete volunteers participated in present study. Written questions asked techniques were used for data collection. Questionnaire collected personal knowledge and assessed fluid consumption of subjects. To compared NTD and TD fluid consumption was used independent samples t-test.Female athletes in NTD and TD intake water 1066.4 ml/day (47.5%) and 1518.4 ml/day (51.4%), tea 386.1 ml/day (17.2%) and 534.7 ml/day (18.1%), fruit juice 175.1 ml/day (7.8%) and 239.3 ml/day (8.1%), energy drinks 40.4 ml/day (1.8%) and 85.7 ml/day (2.9%), respectively. Male athletes in NTD and TD intake water 1192.1 ml/day (48.4%) and 1653.7 ml/day (52.1%), tea 445.8 ml/day (18.1%) and 568.1 ml/day (17.9%), fruit juice 169.9 ml/day (6.9%) and 241.2 ml/day (7.6%), energy drinks 54.2 ml/day (2.2%) and 98.4 ml/day (3.1%), respectively. Male subjects consumed 28.9% more fluid in TD (3174 +/- 46.3) than NTD (2463 +/- 32.1 ml/day). Female subjects consumed 31.6% more fluid in TD (2954 +/- 35.4) than NTD (2245 +/- 45.2 ml/day).Adequate fluid consumption, especially water intake is very important for athletes. Athletes have been increased fluid intake in training days. Water is the most increased fluid. This may be related to excessive sweating of athletes during exercise.Publication Examining the relationship between multistage 20 m shuttle run test and running tests performed at different distances(Drustvo Pedagoga Tjelesne & Zdravstvene Kulture, 2017-06-28) Alparslan, Tuncay; Arabacı, Ramiz; Çankaya, Cemali; Alparslan, Tuncay; ARABACI, RAMİZ; ÇANKAYA, CEMALİ; Spor Bilimleri; Fizik Eğitimi ve Spor Öğretmenliği Bölümü; 0000-0003-2164-0085; ABI-4831-2020; AAA-3736-2022; CIH-6673-2022Military staff are required to have a high level of fitness to be able to cope with the physical challenges of his profession to perform the tasks assigned to him and to be protected from the possible injuries. Therefore, their strength and cardiovascular endurance parameters are measured and evaluated by tests. The aim of present study was to determine the relationship between the multistage 20 m shuttle run test(MSRT) and 1200 m, 1600 m, 2400 m running tests performed on the military high school students and the number of shuttles that counterbalance different running times. In present study, 588 volunteer military school students were recruited in this study and categorized in 3 groups according to age. In the first group (G1) 15 ages (n = 168, height 171 +/- 6,22 cm, weight 64 +/- 8.69 kg), in the second group (G2) 16 ages (n = 121, height 175 +/- 5.14 cm, weight 65 +/- 7.21 kg) ad the third group (G3) 17 and 18 ages (n = 300, height 177 +/- 5.18 cm, weight 70.5 +/- 7.55 kg) took place. G1, G2 and G3 groups performed 1200 m, 1600 m, 2400 m running tests, respectively the running speed were set. All of the students performed the shuttle run test two days later. The relationship between the number of shuttles and running speed were analyzed by multiple regression analysis. It determined following formulas. Formula 1: 1200 m n of shuttles for running = (6.893 x 1200 m running speed (km.h(-1))) + (-22.513), Formula 2: 1600 m n of shuttles for running = (8.889 x 1600 m running speed (km.h(-1))) + (-43.548), Formula 3: 2400 m n of shuttles for running = (7.691 x 2400 m running speed (km.h(-1))) + (18.410). In conclusion, there are positive relationship between the shuttle run test and 1200 m, 1600 m, 2400 m running tests. Also, we can say military high school students could be used the shuttle run test instead of other distance running tests to determine cardiovascular endurance.
